# Bulk cPanel Self-Hosted Email Detection

> Bulk cPanel Self-Hosted Email Detection is a paid API for AI agents from email.intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-24).

Checks up to 20 domains concurrently to determine whether each domain's email is hosted by cPanel's self-hosted mail server, returning ordered results with per-item error fields and a failure count.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability bulk-cpanel-self-hosted-email-detection-ca7751a4
```

Example prompt: Can you check this list of domains — acme.com, globalco.net, shopify-alt.io — and tell me which ones are running their own cPanel mail server? I've got about 15 domains to check all at once.

## When to prefer this

Use this endpoint when you have a list of 2–20 domains to check simultaneously for cPanel self-hosted email, rather than making 20 sequential single-domain calls. It processes concurrently and preserves input order, making it ideal for batch enrichment workflows, lead scoring pipelines, or infrastructure audits where latency and throughput matter.

## Known failure modes

- Domain not resolvable — MX lookup fails, per-item error field populated
- Batch exceeds 20 domains — request rejected or truncated
- DNS timeout via Cloudflare DoH — per-item error returned
- Invalid domain format in input list — per-item error populated
- All items fail — failure count equals batch size with empty positive results

## How this service works

Bulk is email hosted by cpanel self hosted: up to 20 domains in one call, processed concurrently, results in input order with a per-item error field and a failure count. Same answer per item as the single endpoint. Batch enrichment for agents that hold a list. $0.10 per batch.

## Output

An ordered array of results matching the input domain list, where each item indicates whether the domain's email is hosted by cPanel's self-hosted mail solution (same answer as the single-domain endpoint), plus a per-item error field for any lookup failures and an overall failure count for the batch.
